Abstract

A comparative analysis and mathematical modeling of laboratory animal sensitivity (mice, rats, rabbits and dogs) to microwave exposure in the dependence of the power flux density (PFD) and the specific absorption rate (SAR) were carried out. The results obtained in our laboratory and some data published by other authors were presented as the dependence of the survival time of various animals during exposure both on PFD and SAR of microwave radiation (0.46; 2.4 and 7 GHz). It is shown that if PFD is used as a dosimetric parameter, the animal sensitivity to nonionizing electromagnetic ultrahigh frequency radiation increased with animal mass. If SAR was used as a dosimetric parameter, the arrangement of animals in accordance with their sensitivity to microwave became quite opposite. Mathematical equations describing the dependence of the survival time of laboratory animals on the duration and the intensity of microwave radiation were obtained. These equations describe the published experimental data and can be used to predict the animal death during the process of microwave irradiation.

摘要

对实验动物(小鼠、大鼠、兔子和狗)在功率通量密度(PFD)和比吸收率(SAR)依赖情况下对微波暴露的敏感性进行了比较分析和数学建模。将我们实验室获得的结果以及其他作者发表的一些数据呈现为各种动物在暴露期间的存活时间与微波辐射(0.46、2.4和7吉赫兹)的PFD和SAR的依赖关系。结果表明,如果将PFD用作剂量学参数,动物对非电离电磁超高频辐射的敏感性随动物体重增加而增加。如果将SAR用作剂量学参数,动物对微波敏感性的排列则完全相反。获得了描述实验动物存活时间与微波辐射持续时间和强度依赖关系的数学方程。这些方程描述了已发表的实验数据,可用于预测微波照射过程中动物的死亡情况。
